bodyParser.json with custom type application/*+json return an empty body

I’m developing a HTTP server to interface with oneM2M. The header of the POST request received by oneM2M are:

content-type: 'application/vnd.onem2m-ntfy+json'
content-length: 441

Here the HTTP server code:

var express = require('express');
var bodyParser = require('body-parser');
var port = 3331;

var app = express();
								
app.use(bodyParser.urlencoded({
    extended: false
}));
app.use(bodyParser.json({
    type:'application/vnd.onem2m-ntfy+json'
}));
                                
app.listen(port);
console.log('SERVER LISTENING ON PORT ' + port);
console.log();
						
app.post('/', function(req, res) {
    console.log("REQUEST");
    console.log(req.body);
    console.log();
    res.status(200).send('OK');
});

The received body is empty. It is strange because in the request POST header content-length is not 0 and content-type defined for the bodyParser is the same in the POST header! Could you help me to solve this issue?

Kind regards, Luca

Too old version

P.S. if you’re using Express 4.16.0+ you don’t even need to require the body-parser separately, since it’s included now:

var express = require('express');
var port = 3331;

var app = express();
								
app.use(express.urlencoded({
    extended: false
}));
app.use(express.json({
    type:'application/vnd.onem2m-ntfy+json'
}));
                                
app.listen(port);
console.log('SERVER LISTENING ON PORT ' + port);
console.log();
						
app.post('/', function(req, res) {
    console.log("REQUEST");
    console.log(req.body);
    console.log();
    res.status(200).send('OK');
});
